DUST-CATCHING RADIATOR-CAP.

isomer...

Application filed July 19, 1918; Serial No. 245,637.

To all whom it may concern.

Be it known that T, WALTER A. Eoxnn, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Dust-Catching Radiator-Caps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to caps for radia tors and the object thereof is to filter dust from the heated air before it is circulated.

Briefly, the invention comprises a cap to fit over the upper portion of a radiator and having therein a textile filter positioned above the radiator to remove dust, the top of the cap being perforated for the escape of the filtered alr.

Tn the drawing:

Figure 1 is a frontelevation showing the cap applied to a radiator, this view being indicated by line l-1, of Fig.

Fig. 2 is a vertical section indicated by line 22 of Fig. 1.

Fig. 3 is an enlarged View of the main or upper portion of the cap alone corresponding to line 33 of Fig. 1 and showing the same partly in side elevation and partly in section.

Fig. 4 is a horizontal section indicated by line H of Fig. 1 showing the manner of securing the cap in position on the radiator.

Fig. 5 is a plan of the filter.

Fig. 6 is a fragmentary section indicated by line 66 of Fig. 3.

The invention comprises a rear member 12 constituting a standard which extends upwardly in the rear of the radiator A to form the back of'the cap proper which has a depending front wall 13 and a curved top 14 provided with perforations 15 for the escape of the filtered hot air. End walls 16 are provided and one of these has a horizontal slot 17 cove ed by a hinged door 18 havlib ing a pocket 19.. This slot is provided for the introduction and removal of a textile fabric filter 20 which is located in horizontal position above the radiator. A suitable fabric for the filter is muslin but any other fabrics which will satisfactorily separate the dust from the air passing therethrough Specification of Letters Patent.

Patented May a, we.

may be used. The edges of the filter are secured in split tubes 21 which are in turn slid into split tubes 22 secured on opposite sides of the interior of the cap. The ends of the tubes 21 protrude into the pocket 19 of the door 18, whereby they may be readily grasped when the door is opened. By this or similar arrangement the filter cloth may be readily removed for cleaning or replacmg.

To position the cap on the radiator a block 25 is mounted in horizontal position in. each end of the cap, this block being of sufficient thickness to fill the space between the cap end and the adjacent radiator section. A screw bolt 26 passes through the block 25, extends between the parts of said, radiator section and engages another block 27. Both blocks are sufficiently long to span the parts of the radiator section, so that tightening of the bolt will secure the cap to the radiator. I

In operation the heated air passing up around the radiator enters the cap, passes through the filter which removes the dust therefrom, and leaves the cap through the perforations 15. The air in a room is thus materially improved especially whereTadiators are used, in which cases the greater portion of the air is circulated again and again.

In order to improve the draft through the cap, side members 30 extend forwardly from the rear member 12, their front edges 31 being forward of the member 12 a little less than half the depth of the cap.

I claim:

1. A radiator cap adapted to inclose the upper portion of a radiator and extend create a draft, the cap being open at its top and bottom. a filter slidablyand removably mounted within the cap entirely filling it horizontally, and supported directly above the radiator and directly below the top of the cap. whereby heated air will have an unobstructed vertical passage from the radiator to the filter and from the filter to and through the top of the cap.

2. A radiator cap adapted to inclose the upper portion of a. radiator, the cap being also adapted to inclose the back andparts of the sides of the radiator and extend down to the floor, a. filter slidably and reniovably mounted within the cap entirely covering its horizontal area and supported directly above the radiator and directly below the top of the cap, the cap being open at the bottom, and having its top perforated, whereby heated air will have an unobstructed \ertical passage from the radiator to the filter and from the filter to and through the open top of the cap.

3. A radiator cap adapted to inclose the upper-portion of a radiator, the cap being open at the bottom and having its top perforated for the passage of heated air therethrougln a horizontally positioned air filter extending across the interior of the cap and slidably supported by the Walls thereof, the

filter being positioned to lie above the top 5 close said opening having a recess therein to 20 accommodate the extending end of the filter. In testimony whereof I affix my signature.
